DONALD BARNS MORISON, OF HARTLEPOOL, -ENGLAND.

COOLING-TOWER.

Application led June 18, 1909. Serial No. 502,971.

To all whom it may concern:

Be it known that I, DONALD BARNS Moni- SON, a subject of the King of Great Britain and Ireland, residing at Hartlepool Engine lVorks Hartlepool, in the county of Durham, ngland, have inventedcertain new and useful I'In'lprovements Relating to Cooling-Towers, of which the following is a specification. My invention relates 'to means for distributing and. collecting the Water in -water cooling towers, my object being to repeatedly distribute the water with vgreat uniformity-over the 4whole horizontal sectional area of the tower and in a manner conducive to great cooling effect without the use of apparatus likely to get out of order through impurities in the water, corrosion or otherwise. i My invention consists` in combinations of apparatus, which will' be described in the following specification and ,more particularly set forth in the annexed claims.

Referring to the accompanying drawings, Figure 1 is a vertical section through a cool- V ing tower .provided with apparatus according to my invention. Figs. 2, 3 and 4 show in vertical section alternative forms of water discharge nozzle. Fig. 5 is a vertical section through three nozzles, sprayers and troughs. Figs. 6 and 7 8 and 9, 10 and 11, and 12 and 13 are respectively vertical 4sections and plans of distributing plates or sprayers adapted to receive the water dis.- charged `from the nozzles. Figs. 14r18 illustrate the action o f the sprayer shown inFi'aand'., l

Re erring to Fig. l-a is the water supply, pipe, which .delivers the water to be 450 cooled into the tower. The water is con! yveyed ,from this'supply pipe a', by way of 'the supply trough b, to the main longitudinal trough e, which extends practically the whole length of the tower. Communicating 45 withthis longitudinal trough c are a series,

:of distributing troughs d, d, of which two only areshown, the Aothers being parallel to these.

longitudinal trough c, nearly 'to the sides of the tower and are provided with nozzles e, e,

These distributing troughs, which will hereinafter be referred toas thepr1 mary distributing troughs, extend from the plates or sprayers f, f, are arranged one under each nozzle, these sprayers being adapted to receive and distribute the water discharged by the nozzles, as illustrated in F ig. 5. Inclined planes g, y, are arranged below the sprayers to receive the water thrown upward and outward by the latter and deliver it into a second series of troughs lz., la., hereinafter referred to as the secondary distributing troughs Severahsets of second- ,ary troughs are provided in the tower, each being furnished, like the primary troughs, with discharge nozzles and sprayers, and

,collecting lplanes being arranged between each set of troughs, the arrangement being clearly shown in Figs. 1 and 5.

.The planes g, g, extend upward in a diagonaldirection, each springing from, or from just above, a secondary trough which is parallel to it. The planes are advantageously constructed, as shown in Fig. 5, ofa series of boards n, fn, each horizontal as regards its length but sloping laterally and arranged in echelon, one above the other, so that each delivers the water on to the board next below it, except for the lowest board which discharges into the trough, and spaces being provided between the individual boards for the passage of'/ air. Auxiliary planes k (Fig. l) may be ,provided to guide inwardly the water thrown' on or toward the sides of the tower.

The water may be allowed to overflow I from the ends of the last set of secondary troughs to the tank m, at the bottom of the tower.

lThe nozzles, hereinbefore referred to, may be variously constructed; but, ,in order that the sprayers may act effectively, it is desirable that each sprayer should receive a solid jet or rope of water and, with this object in View, the nozzles are preferably' constructed with van outlet end of smaller sectional area than the inlet end;

convenient designs of nozzle are shown in Fig. 2, 3 and 4. Moreover, in order to assist,

the entry of the water into the nozzle, the

latter may be provided with an enlarged portiono, at its upper end, as shown in Figs. 3 and 4, and may be cut away on the side at which the water, enters, as shownI in Figs. 2 and 3. The nozzles are conveniently supported on the" bottoms of the troughs vby means `of shoulders or flanges p. In the nozzle shown in Fig. 3, the main portion iS intended to be constructed of cast iron, provided with an exit converging member g formed of orcelain.

A very e cient form of distributing plate or sprayer is shown in Figs. .6 and 7. The

plate is shaped like a crown wheel with a flat central portion 7 and a peripheral ser` rated ridge s. The interior face t-of this ridge is inclined at a small angle to the yverv tical-or may in some cases be quite Vertical-and is connected with the atrsurface u of the body part of the plate by a small curve .or chamfer v The jet of Water is directed from the nozzle against the center of the upper flat surface u and spreads out in a film which is deflected upward by the chamer and distributed by the serrated ridge. To illustrate this distributing action, partial sections of the plate are shown in Figs. 14, 15, 16 17 and 18, these sections being respectively on the lines AA, BB, CC, DD and EE, of Fig. 7; and it will be seen by reference to these figures that the water is .thrown outward to a varying extent according to the portion of the ridge which it strikes. By this means, not only is the water inely divided and spread to a considerable distance around thesprayers; but, owing to its varying treatment by the dii'erent portions of the peripheral ridge, it practically covers, in falling, the whole area within the4 circle or boundary passing through the outermost drops. Moreover, the water is projected upward to a considerable height above the sprayers and, being in a ine state of division, is in the ai`r for a considerable period, the cooling elect due to this period of suspension being, in the case of water cooling towers, very appreciable.

Figs. 8 and 9 are respectively a vertical section and plan of a. modified form of sprayer wherein the Hat body part 1' and the -upwardly extending peripheral ridge s are retained; but the peripheral ridge in this case is of uniform height, and radial ridges w are formed onthe upper surface'of the body, extending and vincreasing in depth v from the center of the plate to the periphery.

It is desirable to keep theA spray as far as possible from striking the sides of the tower if the latter is of theclosed-in type, or of A passing out at the sides if the tower is of nozzles for said trou hs, -a set of sprayers in line with said nozzIe and upon which the discharged water impinges to be distributed, a set of planes recelving the water distributed by said sprayers, and a set of secondary troughs receiving the water from said planes, substantially as described.

bers of each set being arran ed horizontally I and lthe sets being arrange vertically, discharge nozzles for said troughs, sprayers in line with said nozzles to receive and distribute the water discharged by said nozzles, and planes receiving the water distributed by said sprayers and delivering this water into said troughs, substantially as described.
